A third of food bought in cities is thrown away. Busy households over-buy, forget leftovers and misread expiry dates, while nearby people go hungry. The causes are spread across shopping habits, storage, and culture.

Design a community program that reduces household food waste in urban neighborhoods. Study who is affected, dig past the obvious symptoms to the real root causes, and design a solution that could actually work in the real world. There is no single correct answer — what matters is the quality of your thinking, the stakeholders you consider, and how clearly you justify your chosen direction.

• Who is most affected by this problem, and how did you account for them?
• What is the single biggest risk to your solution working?
• Which assumption, if wrong, would break your whole idea?
